Answer:
- <u>1,000W</u> (rounded to one significant figure)
Explanation:
I will answer in English.
The question is:
- <em>What is the power of a filament lamp that connects to the 220 V network, knowing that it has a resistance of 50 ohms?</em>
<em />
<h2>Solution</h2>
<em />
<em>Power</em>, <em>voltage</em>, <em>resistance</em>, and current, are related by either of the following equations:
Where:
- R is resistance in ohms (Ω)
- V is voltage in volts (V), and
- I is current in amperes (A)
Since you know the voltage (<em>220V</em>) and the resistance (<em>50Ω</em>), you can use the last equation:
Since the magnitude 50Ω has one significant figure, your answer should be rounded to one significant figure. That is <u>1,000W.</u>

You would use the Lookup field to store a value from another table.
Answer:
Cluster Column Charts.
Explanation:
Clustered column chart:-It displays multiple data series in separate vertical columns. Each series have the same axis labels.Clustered vertical columns thus allow direct comparison of multiple data series.When having three data series you can compare their heights also.So we conclude the answer is Cluster Column Charts.
